3.2. VGP’s and Pole Migration
Virtual geomagnetic pole (VGP) shows the position of the geomagnetic
paleopole (Lanza and Meloni, 2006). Virtual geomagnetic pole’s (VGP)
latitudes from this data set show fluctutions in Matuyama section
(Figure 7). These values indicate 90o change from
Matuyama to Brunhes transition as a result of pole migration (Figure 7).
In additon, we plotted VGP path for Matuyama, Brunhes and transition
sections using VGP latitudes and longtitudes based on characteristic
remanent magnetization (ChRM) directions detected in our samples (Figure
8). VGP locations for Matuyama section is in the southern hemisphere
(Figure 8). During the transition from reversed to normal polarity,
magnetic pole migrates from southern to northern hemisphere (Figure 8).
After the geomagnetic transition, paleopoles fluctuate around geographic
north pole (Figure 8). This VGP path of pole migration during the
transition from the southern to northern hemisphere compares well with
the Matuyama-Brunhes transition found by Okada et al. (2017) recorded in
marine sediments near Japan (Figure 8).
